The undiscovered recoverable natural garesources in China are estimated to be 19. 27x10m,. Natural gas is mainly distributed in the middle andwest China and offshore areas of china. The Tarim Basin. Sichuan Basin. Ordos basin. East China SeaBasin, Tsaidam Basin, Yinggehai Basin, and Qiongdongnan Basin are the main gas-bearing basins. Thenatural gas resources are not distributed evenly and are under-explored in China. The deeper horizons ineast China, foreland basins and craton paleo-uplifts in the middle and west China, and the offshore basinsare the main exploration areas in the futureKey words: Natural gas, resources, exploration area, China1 Introduction25.7% in offshore petroleum province and only 6.63% ineastern petroleum provinceThe recoverable natural gas resources of China estimatedy many researchers are generally 10x102-14x10 2 m(Zhai, 2.2 Distribution in basins2002; Shen et al, 2000; U.S. Geological Survey World EnergAs shown in Table 2. the undiscovered recoverable naturalAssessment Team, 2000). A recent investigation on recoverygas resources are mainly distributed in the following 7 basinsrate of oil gas resources in the new round of national The Tarim Basin, the Sichuan Basin, the Ordos Basin. thend gas resources assessment of China has made a east China Sea Basin, the Tsaidam bathe Yinggehai Basinsignificantly increased estimation of the potential recoverable and the Qiongdongnan Basin. The undiscovered recoverablenatural gas resources, and the volume of the technically natural gas resources of other 108 basins account for 24.0%recoverable natural gas resources was estimated to beThe undiscovered recoverable natural gas resources in thethe range of 154x10 2-310x10 2m, with a mean of 22.0 Tarim Basin are the largest, with a volume of 5.40x10 2 m3012 m3, significantly higher than 12.75x102m, which was and account for 28.0% of the total undiscovered recoverableestimated in the second assessment of national oil and gas natural gas resources in China. The undiscovered recoverableresources of China in 1994(Zhao et al, 2005: Zhang, 2004), natural gas resources in the Sichuan Basin, the Ordos Basinand higher than 14x10m', which was estimated by China and the east China Sea basin each account for more thanAcademy of Engineering(2004)2 Distribution of undiscovered recoverable 3 Main exploration areasnatural gas resourcesn recent years, with the development of science and2.1 Distribution in petroleum provincestechnology and the theory of hydrocarbon exploration arTill 2004 year-end, the cumulative total recoverable development, many big gas fields have been discovered, suchnatural gas reserves in China are 2.76x1012m'(Shao et al, as the Kela-2, Sulige and Puguang gas fields (Li et al, 20042005), and the undiscovered recoverable natural gas resources Song and Liu, 2006), showing good exploration prospect forare estimated to be 19.27x1012 m3 which accounts for 87.6% gas resources in China.
